A wonderful tour with two fantastic swimming stops, including some very close encounters with the fish 😎. Highly recommended for families, couples, or even solo travelers who love swimming. Great atmosphere on the boat, perfect for families. Since the boat is a bit smaller, the trip, with a maximum of 50 people, feels quite intimate. The friendly and spontaneous rebooking, offered as a courtesy, is particularly noteworthy. P.S. The sailboat is powered by a motor. The only downside ;).

Small boat, plenty of time to swim, and the skipper did his best to locate the turtles for us.

It was a fantastic boat trip at a great price! At first, there was a long queue, and we wondered how it would all work out. But the trip was worth it in no time, and we all had a seat on the boat where we could see everything. The guide was excellent; he turned the boat around so everyone could enjoy the view. We saw three turtles, and then we continued on to stunning natural scenery: turquoise water, caves, and rocky outcrops. It was simply fabulous. Finally, jumping into the crystal-clear water from the boat was a refreshing and amazing experience! For the last 20 minutes, we went to the beach, where we could see the turtle nesting sites in the distance. For those of us who hadn't dared to jump in the water, like me, this was a great opportunity to hop into the beautiful water! Recommendation: bring plenty of water and, especially for children, food! I'd love to do it again!

An incredibly fun boat trip with a great captain. A unique kind of boat with a glass bottom so you could see the turtles swimming beautifully. Dog-friendly!

I highly recommend Happy Days Zante. Great value for money, the company organises to pick you up from a convenient location in a small, clean charter bus. The boat was not over crowded and the sites visited by boat were amazing. This trip didn’t feel overly touristy, perfect for those who want to enjoy the sites without the big crowds. The stop over at the olive tree was also beautiful. We were then taken back to the original pick up spot. Amazing day!
